Definitions

  • the present invention relates to a method for prevention rollover when an aircraft or spacecraft lands, especially one manned or unmanned Capsule or a guided missile, which is the earth's surface approaches in the braked or unbraked case or in flight with the help of an airbag landing shock damping system, which before is inflated with gas during the landing and from which during the Landing through exhaust gas exits.
  • DE-C-33 23 348 is a landing shock absorber for missiles known, the rate of descent during the landing process a brake parachute is determined and its impact on the Floor by using air cushions in the form of inflatable Tubing is reduced.
  • the landing pad is there from a plastically deformable tubular film, one of which End turned in and pulled through the other end, see above that between the walls of the nested ends one Opening for introducing a compressed gas is created.
  • This impact cushion offers increased lateral stability, so that the pressure increase resulting from the impact of the load a plastic deformation of the material is reduced and a throwing back the load is largely avoided.
  • DE-A-30 24 551 is a landing shock absorption system for load bodies returning from the airspace known in the gas-filled attenuators from resilient Material can be used that folds up when not required and are self-sufficient during the unfolding Fill in with ambient air, taking care when hitting the earth briefly compressing the air filling and then blowing it out Attenuators are provided.
  • airbag landing shock damping systems the advantage of being relatively light, easy to take up little space when set up and inactive.
  • a gas-filled damping system comes as the airbag landing shock absorption system toroidal or rectangular gas container in question, which is inflated before landing.
  • the desired damping effect achieved by a medium with which the airbag landing shock absorption system is filled i.e. Air or another gas during the actual landing, i.e. when touching the ground, depending on the Sink rate, the mass of the aircraft or spacecraft and the desired delay is canceled. This can by opening suitable drain valves.
  • landing means a high risk of rollover Aircraft or spacecraft, especially with missions sensitive measuring devices or even passenger transportation is to avoid.
  • the object of the present invention is to propose a method with which the rollover during landing with Security is prevented.
  • This compensating moment acting in the + Y direction can by Utilization of the compression energy and appropriate control the gas state can be realized in the individual chambers.
  • the Pressure in the forward chambers provided in the direction of flight if possible be large and as small as possible in the rear chambers.
  • Figure 1 shows a bottom view of an inflated toroidal Airbag landing shock absorption system which in a variety is divided by chambers, which seen in the direction of flight front chambers with 1 'and seen in the direction of flight rear chambers are designated 1.
  • 1 and 2 are the ones lying in front in the direction of flight F. Sections with a and those at the back in flight direction F. Sections labeled b.
  • Vx is the horizontal speed referred to that without compensation to a rollover of the landing aerospace body 3 can lead.
  • the exhaust valves are actuated in such a way that a pressure difference between the chambers 1 'located at the front in the direction of flight F with respect to the chambers 1 at the rear in the direction of flight F is set such that the chambers 1' at the front have a higher pressure have on landing than the rear chambers 1.
  • the airbag landing shock damping system according to the invention is suitable However, they are equally good for reducing air or impact Preferred space devices.
  • the on a payload hanging from a paraglider is basically an orientation in the horizontal flight direction. This country orientation is known from the start, i.e. that the device on one Paraglider hanging towards the ground with known flight direction Landing begins; it is also possible to change the preferred direction already before landing and e.g. through a position control or to maintain engine control.
  • the airbag system can be optimized.
  • the airbag landing shock damping system 2 also exists here from several chambers 1, 1 ', the pressurization of the individual chambers according to the country orientation.
  • Each Chamber is in turn equipped with exhaust valves that either by means of pressure sensors, accelerometers or Touch sensors are triggered if it is active controlled exhaust valves, e.g. Pyrovalves, trades or else triggered at a certain pressure, provided that it is passively controlled exhaust valves, e.g. those with rupture discs acts.
  • a pressure difference is set in the chambers 1 'located at the front in the direction of flight F such that they have a higher pressure than the chambers 1 at the rear in the direction of flight F, which have a lower pressure.
  • this can be done during landing by the fact that open the outlet valves of the rear chambers 1 at a lower excess pressure than the outlet valves of the front chambers 1 ', open the exhaust valves out of phase, ie the exhaust valves of the rear chambers open earlier than those of the front chambers, Setting a smaller discharge cross-section in the outlet valves of the front chambers compared to that of the rear chambers.
  • Another way of flipping over aerospace equipment to prevent with preferential direction consists in even before landing the gas pressure in the front chambers 1 ' to a higher value than in the rear chambers 1 or another gas for the front chambers 1 ' use as in the rear chambers 1, e.g. for the air in the front chambers and helium in the rear chambers will, causing different outflow velocities can be reached through the exhaust valves.
  • the gas pressure can also be increased by igniting gas generators in the front area to be increased above the known Measures are triggered; either on impact or briefly beforehand after determining the landing orientation.
